[0002] With the rapid iteration and popularization of intelligent robot technology, the research and development, sample processing and mass production testing of intelligent robots are becoming more and more refined and sophisticated. In the research and development and production of intelligent robot parts, various irregular and high-precision components need to be shaped and angled by cutting equipment.

[0005] The present invention has the following beneficial effects: (1) By setting up a multi-directional positioning part, the positioning component and the elastic component work together. Under the linkage drive of the square slider of the driving part, the two sets of mirrored multi-directional positioning parts first move towards each other. The positioning plate 1 moves synchronously to complete the centering of the workpiece in the left and right directions. The positioning plate 1 then locks and stops. The rectangular plates continue to slide towards each other, so that the rectangular slide plate slides relative to the rectangular plate. Through the sliding cooperation of the inclined groove and the inclined surface of the cylindrical slider, the L-shaped rod is driven to move stably in opposite directions under the limiting constraint of the U-shaped limiting slider, which drives the positioning plate 2 to close and clamp the workpiece, realize the front and rear orientation positioning of the workpiece, and finally complete the all-round limiting of the workpiece in the left and right and front and rear directions. During the positioning process, the spring damper 1 moves with the relative movement of the structure and compresses and stores energy to provide elastic force for the subsequent structure reset. Thus, the workpiece's freedom can be constrained in all directions, greatly improving the workpiece clamping stability, effectively avoiding the workpiece shifting or misaligning during laser cutting, and improving the overall cutting operation stability and finished product qualification rate. (2) By setting up a pressing part, the hinge assembly and the pressing assembly work together and are carried out in sync with the positioning process of the multi-directional positioning part. During the movement of the rectangular plates towards each other, the top fixed frame is moved synchronously, causing the hinge rod to deflect at an angle, and then pushing the rectangular slider to move vertically and stably down along the fixed block. When the rectangular slider moves down, the spring damper 2 inside the rectangular groove is compressed, buffering and adjusting the downward pressure, driving the rectangular connecting slider to slide along the groove, and finally driving the pressure block to press vertically on the surface of the workpiece, thus forming a vertical pressing and fixing after the workpiece is positioned. Combined with the multi-directional positioning structure, a three-dimensional fixing effect is formed, eliminating vertical jumping and loosening of the workpiece, avoiding cutting vibration problems, and further improving the overall cutting operation stability and finished product qualification rate. (3) By setting up a drive unit as the core of the overall power drive of the device, it is composed of a fixed block two, an electric telescopic rod, a slide rod, a hinge rod two, a square slider, a guide slide groove and a telescopic protective cover two. During operation, the electric telescopic rod supported by the fixed block two extends and retracts, driving the end slide rod to move back and forth. Then, through the hinge transmission of the two sets of hinge rod two, the linear power is converted into symmetrical opposing sliding force, driving the two square sliders to slide stably in opposite directions or away from each other along the guide slide groove on the top of the support plate. At the same time, the telescopic protective cover two extends and retracts synchronously with the slide rod, sealing and dustproofing the guide slide groove, thereby realizing the synchronous symmetrical transmission of the double-sided structure, driving the positioning and pressing processes to operate in conjunction. It can ensure that the positioning and pressing actions on both sides are highly synchronized, avoiding the workpiece positioning deviation caused by the deviation of the action on one side, and ensuring the stability and reliability of the whole set of fixing processes.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0010] Example 1, please refer to Figure 1 - Figure 8 The present invention is a cutting device for the research and development of intelligent robots with adjustable cutting angle, including a housing 111 and a support plate 112 fixedly connected to the inner wall of the housing 111, and further including: a cutting part 1, two multi-directional positioning parts 2, two pressing parts 3 and a driving part 4; the cutting part 1 is disposed on the housing 111, the two multi-directional positioning parts 2 are mounted in a mirror image on the top of the support plate 112, the two pressing parts 3 are mounted in a mirror image above the support plate 112, and the driving part 4 is mounted on the support plate 112; The multi-directional positioning part 2 includes a positioning component 21 and an elastic component 22. The positioning component 21 is disposed on the top of the support plate 112, and the elastic component 22 is disposed on the positioning component 21. The positioning component 21 includes a rectangular plate 211, a first positioning plate 212, a rectangular sliding plate 213, two inclined slides 214, two cylindrical sliders 215, an L-shaped rod 216, and a limiting member. The rectangular plate 211 is disposed on the top of the support plate 112, and the bottom of the rectangular plate 211 contacts the top of the support plate 112. The first positioning plate 212 is disposed to the right of the rectangular plate 211, and the rectangular sliding plate 213 is fixedly connected to the left side of the first positioning plate 212, with the rectangular sliding plate 213 penetrating through the rectangular plate 211. Plate 211, two inclined slide grooves 214 are both formed on rectangular slide plate 213, the outer walls of two cylindrical sliders 215 are slidably connected to the inner walls of the two inclined slide grooves 214 respectively, the outer walls of the two cylindrical sliders 215 are fixedly connected to the two L-shaped rods 216 respectively, and a limiting member is set on the left side of rectangular plate 211; the limiting member includes two U-shaped limiting sliders 217 and two positioning plates 218; the two U-shaped limiting sliders 217 are fixedly connected to the left side of rectangular plate 211, the inner walls of the two U-shaped limiting sliders 217 are slidably connected to the outer walls of the two L-shaped rods 216 respectively, and the two positioning plates 218 are fixedly connected to the two L-shaped rods 216 respectively; The elastic component 22 includes two spring dampers 221 and a telescopic protective cover 222; the two spring dampers 221 are fixedly connected between the rectangular plate 211 and the positioning plate 212, and the telescopic protective cover 222 is fixedly connected between the rectangular plate 211 and the positioning plate 212.
[0011] During operation, the two sets of mirrored multi-directional positioning parts 2 first move towards each other, and the workpiece is centered in the left and right directions by the synchronous displacement of the positioning plate 212. The positioning plate 212 then locks and stops. Subsequently, the rectangular plates 211 continue to slide towards each other, so that the rectangular slide plate 213 slides relative to the rectangular plate 211. Through the inclined sliding groove 214 and the inclined surface of the cylindrical slider 215, the L-shaped rod 216 is driven to move stably in opposite directions under the limiting constraint of the U-shaped limiting slider 217, which drives the positioning plate 218 to close and clamp the workpiece. By setting up a multi-directional positioning unit 2, the front and rear orientation positioning of the workpiece is realized, and the omnidirectional positioning of the workpiece is finally completed. During the positioning process, the spring damper 221 compresses and stores energy as the structure moves relative to it, providing elastic force for the subsequent resetting of the structure. This can constrain the workpiece's degree of freedom in all directions, greatly improve the workpiece clamping stability, effectively avoid workpiece displacement and misalignment during laser cutting, and improve the overall cutting operation stability and finished product qualification rate.
[0012] Example 2, please refer to Figure 1 - Figure 8 This invention relates to a cutting device for developing an intelligent robot with an adjustable cutting angle. Based on Example 1, the pressing part 3 includes a hinge assembly 31 and a pressing assembly 32. The hinge assembly 31 is mounted on a rectangular plate 211, and the pressing assembly 32 is mounted on the hinge assembly 31. The hinge assembly 31 includes a fixing frame 311, a hinge rod 312, a fixing block 313, and a rectangular slider 314. The fixing frame 311 is fixedly connected to the top of the rectangular plate 211, the hinge rod 312 is hinged to the right side of the fixing frame 311, the fixing block 313 is fixedly connected to the top of the positioning plate 212, and the rectangular slider 314 slides through it. The top of the fixed block 313 and the rectangular slider 314 are hinged to the hinge rod 312. The pressing assembly 32 includes a rectangular groove 321, two spring dampers 322, a rectangular connecting slider 323 and a pressure block 324. The rectangular groove 321 is opened at the bottom of the rectangular slider 314. The tops of the two spring dampers 322 are fixedly connected to the inner wall of the top of the rectangular groove 321. The rectangular connecting slider 323 is fixedly connected to the bottom of the two spring dampers 322. The outer wall of the rectangular connecting slider 323 is slidably connected to the inner wall of the rectangular groove 321. The top of the pressure block 324 is fixedly connected to the bottom of the rectangular connecting slider 323. Simultaneously with the positioning process of the multi-directional positioning unit 2, as the rectangular plates 211 move towards each other, the top fixing frame 311 moves synchronously, causing the hinge rod 312 to deflect at an angle, which in turn pushes the rectangular slider 314 to move vertically and stably downward along the fixing block 313. When the rectangular slider 314 moves downward, the spring damper 322 inside the rectangular groove 321 is compressed, buffering and adjusting the downward pressure, causing the rectangular connecting slider 323 to slide along the groove, and finally driving the pressure block 324 to press vertically against the surface of the workpiece. By setting the pressing part 3, a vertical pressing and fixing is formed after the workpiece is positioned. Combined with the multi-directional positioning structure, a three-dimensional fixing effect is formed, which eliminates the vertical jumping and loosening of the workpiece, avoids the problem of cutting vibration, and further improves the overall cutting operation stability and the finished product qualification rate.
[0013] The drive unit 4 includes a fixed block 411, an electric telescopic rod 412, a slide rod 413, two hinged rods 414, two square sliders 415, two guide grooves 416, and two telescopic protective covers 417. The fixed block 411 is fixedly connected to the bottom of the support plate 112, the electric telescopic rod 412 is fixedly connected to the front side of the fixed block 411, the slide rod 413 is fixedly connected to the output shaft of the electric telescopic rod 412, both hinged rods 414 are hinged to the slide rod 413, and the two square sliders 415 are respectively connected to the output shaft of the electric telescopic rod 412. Two hinge rods 414 are hinged together, and two guide grooves 416 are opened on the top of the support plate 112. The inner walls of the two guide grooves 416 are slidably connected to the outer walls of the two square sliders 415 respectively. The two telescopic protective covers 417 are fixedly connected to the two square sliders 415 respectively on the side away from each other. The tops of the two square sliders 415 are fixedly connected to the bottoms of the two rectangular plates 211 respectively. The two telescopic protective covers 417 are fixedly connected to the inner walls of the two guide grooves 416 respectively on the side close to each other. During operation, the electric telescopic rod 412 supported by the fixed block 411 extends and retracts, driving the end slide rod 413 to move back and forth. Then, through the hinge transmission of the two sets of hinge rods 414, the linear power is converted into symmetrical opposing sliding force, driving the two square sliders 415 to slide stably in opposite directions or away from each other along the guide groove 416 at the top of the support plate 112. At the same time, the telescopic protective cover 417 extends and retracts synchronously with the slide rod, sealing and dustproofing the guide groove 416. By setting up the drive unit 4, synchronous and symmetrical transmission of the double-sided structure is achieved, and the drive positioning and pressing processes are linked. This ensures that the positioning and pressing actions on both sides are highly synchronized, avoids workpiece positioning deviation caused by unilateral action deviation, and ensures that the entire fixing process is stable and reliable.
[0014] A specific application of this embodiment is as follows: When in use, first open the hinged door 113 on the front side of the machine box 111, place the workpiece to be cut above the support plate 112, between the two mirror-set multi-directional positioning parts 2; then start the drive unit 4, the electric telescopic rod 412 fixed on the bottom fixing block 411 of the support plate 112 retracts, driving the slide rod 413 on the output shaft to move backward, the slide rod 413 pulls the two hinge rods 414 to rotate, respectively driving the two square sliders 415 to move closer to each other along the guide groove 416 at the top of the support plate 112, and the telescopic protective cover 417 at the guide groove 416 extends and retracts synchronously with the movement of the square sliders 415 to achieve groove protection; During the movement of the square slider 415, the two multi-directional positioning parts 2 are driven to operate synchronously to achieve step-by-step multi-directional positioning. The single-sided structure operates as follows, and the two-sided structure operates synchronously in mirror image: In the initial state, the drive unit 4 drives the two multi-directional positioning parts 2 to move closer to each other through the square slider 415 and the rectangular plate 211, so that the two sets of positioning plates 212 move synchronously towards each other, clamping the workpiece to be cut from the left and right horizontal direction, completing the left and right centering positioning of the workpiece, and the positioning plate 212 then stops moving; thereafter, the two rectangular plates 211 continue to slide towards each other, and the rectangular slide plate 213 continues to slide through the rectangular plate 211, so that the two inclined grooves 214 on the rectangular slide plate 213 are relatively displaced, and the two clamped grooves in the extrusion groove are squeezed. The cylindrical slider 215 slides along the inner wall of the inclined groove 214; the two cylindrical sliders 215 move closer to each other synchronously, correspondingly pulling the two sets of L-shaped rods 216 to move towards each other. The U-shaped limiting slider 217 on the left side of the rectangular plate 211 slides and limits the L-shaped rods 216 throughout the entire process to ensure the stability of the movement trajectory. Finally, the positioning plates 218 at the bottom of the two L-shaped rods 216 move closer to each other, clamping the workpiece to be cut from the front and back direction. Combined with the previous left and right positioning, the workpiece is fixed in all directions. During the entire process of the rectangular plate 211 moving closer to the positioning plate 212, the spring damper 221 between the rectangular plate 211 and the positioning plate 212 is compressed to store energy for the reset positioning plate 212. The telescopic protective cover 222 extends and retracts synchronously to achieve dust prevention. In the above-mentioned multi-directional positioning synchronous process, the pressing part 3 synchronously links to complete the workpiece clamping operation: when the rectangular plate 211 moves, its top fixing frame 311 synchronously follows the displacement, causing the hinge rod 312 to rotate at an angle. The end of the hinge rod 312 pushes the rectangular slider 314 to slide vertically downward along the fixing block 313 at the top of the positioning plate 212. During the downward movement of the rectangular slider 314, the two spring dampers 322 inside the bottom rectangular groove 321 are compressed to buffer the downward pressure, causing the bottom fixed rectangular connecting slider 323 to slide down along the inner wall of the rectangular groove 321, and finally driving the pressure block 324 to press vertically downward and adhere to the surface of the workpiece to be cut, and the workpiece is firmly fixed by the elastic clamping structure. After the workpiece is positioned and clamped, the box door 113 is closed, the cutting unit 1 is started, and the robotic arm 114 on the top of the support plate 112 can adjust its posture in multiple angles and directions, driving the rectangular support block 115 and the mounted laser cutter 116 to move. The cutting angle and position are adjusted according to the workpiece cutting requirements, and the workpiece cutting operation is completed by the laser cutter 116. All components work together in a coordinated manner to achieve integrated operation of workpiece positioning, clamping, and multi-angle cutting. This equipment is particularly suitable for rectangular workpieces such as control board pads, isolation baffles, counterweights, mounting base plates, and limit plates.
